2C65 CB Fail Relay

The 2C65 Series relays are adjustable AC current sensing relays designed for high or low voltage power systems where they can be used in a large number of overcurrent applications.

The 2C65 Series relay is a three pole current detector with independently adjustable sensing circuits driving a common adjustable digital setting timing element. Five (5) status inputs & eight (8) relay outputs are provided as standard to allow the 2C65 to be operated in a number of different configurations:

• Time delayed or instantaneous output contacts;

• Phase segregated or 3 phase output contacts;

• Single phase or 3 phase current initiation inputs;

• Timer initiate input logic;

• Where zero standby burden is required use 2C80 model;
